Method for monitoring and reporting events by media gateways

Abstract

A method for monitoring and reporting events by media gateways comprising presetting the events in the media gateways, monitoring the preset events by the media gateways and reporting the monitoring result to a media gateway controller during operation. The events can include: off-hook, on-hook, dialing, hook flash, network fault, quality alarm, and timer timeout, etc. By presetting the events in the media gateways, a system problem of the media gateways not receiving the events issued by the media gateway controller for various reasons can be avoided. The media gateways can automatically monitor and report the preset events after start up, thereby, improving stability of the system.

What is claimed is: 
     
       1. A method for monitoring and reporting events by a media gateway, comprising the steps of:
 presetting said events to be monitored in said media gateway according to a protocol for presetting said events between a media gateway controller and the media gateway before the media gateway is started up, wherein said events are parameters carried in commands of H.248 or Media Gateway Control Protocol (MGCP); 
 monitoring the preset events by said media gateway; 
 reporting the monitoring result to the media gateway controller when the media gateway detects said preset events during operation; 
 issuing events, relevant parameters and Request IDs to the media gateway by the media gateway controller, during the monitoring of said preset events; and 
 monitoring said events with said relevant parameters and said Request IDs received from said media gateway controller, 
 wherein said events received from said media gateway controller have a life cycle and monitoring said events with said relevant parameters and said Request IDs received from said media gateway controller comprises monitoring said events with said relevant parameters and said Request IDs received from said media gateway controller within said life cycle. 
 
     
     
       2. A method for monitoring and reporting events by a media gateway, comprising the steps of:
 presetting said events to be monitored in said media gateway according to a protocol for presetting said events between a media gateway controller and the media gateway before the media gateway is started up, wherein said events are parameters carried in commands of H.248 or Media Gateway Control Protocol (MGCP); 
 monitoring the preset events by said media gateway; 
 reporting the monitoring result to the media gateway controller when the media gateway detects said preset events during operation; 
 issuing events, relevant parameters and Request IDs to the media gateway by the media gateway controller, during the monitoring of said preset events; and 
 monitoring said events with said relevant parameters and said Request IDs received from said media gateway controller, 
 wherein said events received from said media gateway controller have a life cycle, and monitoring said events with said relevant parameters and said Request IDs received from said media gateway controller comprises monitoring said preset events with said relevant parameters and said Request IDs preset in the media gateway after the expiration of said life cycle. 
 
     
     
       3. A communication system, comprising a media gateway controller and a media gateway,
 wherein the media gateway is configured to:
 monitor events which are preset to be monitored in the media gateway according to a protocol for presetting the events between the media gateway controller and the media gateway before the media gateway is started up, wherein said events are parameters carried in commands of H.248 or Media Gateway Control Protocol (MGCP); and 
 monitor the preset events and report the monitoring result to the media gateway controller when the media gateway detects said preset events during operation; 
 
 wherein the media gateway controller is configured to issue the events, relevant parameters and Request IDs to the media gateway during the monitoring of the preset events; and 
 wherein the media gateway is further configured to monitor the events with the relevant parameters and the Request IDs received from the media gateway controller. 
 wherein the events received from the media gateway controller have a life cycle and the media gateway is configured to monitor the events received from the media gateway controller with the relevant parameters and the Request IDs received from said media gateway controller within the life cycle.
